I can't reproduce this problem using

  sqrtm (rand (256))

on my system.

Sorry, but without a way to duplicate this problem I'm afraid I can't
debug it.  If you can debug it and show that the problem is actually
due to a bug in Octave, then perhaps I can fix it.  Otherwise, I'll
have to conclude that the problem is somewhere else.
